ing at the city of Milwaukee, county ofMilwaukee, and State ofyWisconsin, have invented new andk useful Improvements in Hay-Carriers, -oi whichthe `following Ais a *My-invention' relates to improvements in that class ofjhay-carriers in which the grip'- ping-mechanism is adapted to engage therespective sides "of the pulley-rim of the hoist or tackle block by which the load is elevated tothe carrieryand I'it pertains, among other things, tofthe construction and arrangementv ofa set of `two oppositely-arranged gripping- ,clutches which are adapted vto engage the respective sides of thepulley-rim, means for automatically ithrowing said clutches into flocking engagement with-the rim ofthe pulley, and'means for'also automatically separating the `clutches and releasing "the pulley asthe load carried thereby is'lbrought to the place o'fdischarge.y j The construction of my invention is further explained by reference tothe accompanying drawings, in which-' Figure 1 is a side view of a carrier'embodyl ing the same suspended from a track. Fig. 2

is a transverse vertical Isection drawn on line :c of Fig. 1, showing the pulley disengaged from gripping-clutches.l Fig. 3represe'nts a similar view to that shown in Fig. 2, in which the gripping-clutches are shown in engagement with the pulley. Fig. 4 represents a bottom view of a portion ofthe track andthe stop which is adapted to actuate the clutches.

Like parts are identified by the same reference characters throughout thel several views.

The carrier-track 1, carrier-frame 2, framesupporting rollers 3, stationary stop 4, stopsupporting bracket 5, hoisting-rope 6, and rope-supporting pulleys 7 are substantially ofthe ordinary construction.

My present invention pertainsl more esl pecially to the construction and arrangement of the sheave-block 9, sheave 10, and the gripping mechanism of thefcarrier which is adapted to engage the respective sides of the sheave and from which the sheave and the load is adapted to besuspended as thelload is being conveyed along the track 5 also, to the mechanism for automatically vreleasing the gripping-clutches from the sheave when desirous to lower the load from the carrier.

My grippingy mechanism comprises a set of two gripping-'clutches '11 a'nd 12, which are supported opposite to each other from'the respective 'sides of the upwardly-converging guide-walls 13 upon'the pivots14 l14 in such a manner and in such relations to eachother 'thatfthe' sheave 10 as 'it `is drawn up lby the hoisting-rope betweenthe converging guideywalls 13 'will be `brought in contact with the' lower outwardly-diverging sides of the clutches, whereby said clutches will be 'thrown apart until they periphery of they sheavepasses themwhen said clutches will be automatically thrown toward each other and caused to engagethe respective sides of the sheave -lange'15fby 'the recoil 'of the springs 16 16, whereby vthe sheave, sheaveb'lock, and load suspended from the sheaveblock will when' the hoisting-rope is slack be suspended from `said gripping-clutches 11 and 12 until said clutches are thrown apart by the automatic lactionl ofthe connecting mechanism against the stop/1. The gripping-clutches'll'and 12 are simultaneously thrown apart and out of engagement with the'flanges 15 of the sheave by contact ofthe upper'end ofthe latch 17 with either of the angular contact-bearings 18 ofthe stop. The

latch v17 is centrally supported from the carrier-frame 2 upon thepivot 19. The gripping-clutch 1 1 is provided with an operatingarm 20, which is adapted to contact with the latch 17 above its supportin -pivot, while the gripping-clutch 12 is provi ed with an arm 21, which contacts with said latch 17 below its supporting-pivot, whereby as said latch is thrown outwardly by contact with one of the angular bearings ofthe stop both of said grippingclutches will beI simultaneously thrown Vapart and out of engagement with the sheave-flange, whereby said sheave and its load will, as stated, be free to descend,

when said clutches will be thrown back into' their normal position for engagement with the sheave by the recoil oi said actuatingspring 16. l

IOO

It will be understood that when the latch y 17 has passed over either of the angular surfaces 18 of the stop as itis brought toward IFS latch, whereby the upper arm 24 of said latch will be thrown'out of engagement with said stop, thereby releasing the carrier, when the same may be again drawn along the track.

I-Iaving thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a hay-carrier of the class described the combination of a latch pivotally supported from the carrier-frame and adapted to be actuated by contact with the carrier-stop, two gripping-clutches pivotally supported opposite to each-other near the apex of the pulley-guiding walls, means for automatically throwing said gri ping-clutches into locking engagement with the flanges of the pulley as it is drawn between them, means actuated by said latch as it is brought in contact with said carrier-stop for simultaneously separating said gripping-clutches and disengaging the pulley therefrom. L

2. In a hay-carrier of the class described the combination of a latch pivotally supported from the carrier-frame and adapted to be actuated by contact with the carrier-stop, two gripping-clutches pivotally supported opposite to each other near the apex of the pulley-guiding walls, means for automatically throwing said gripping-clutches into locking engagement with the flanges of the pulley as it is drawn between them, one of said gripping-clutches being provided with an operating-arm adapted to bear upon said latch below its pivotal support and the other clutch being provided with an operatingarm adapted to bear against said latch above its pivotal support, whereby as said latch is thrown laterally by contact with the angular 'wall of the carrier-stop both oi said grippingclutches will be simultaneously thrown out of engagement with the pulley.

3. tIn a hay-carrier or the class described the combination of a latch pivotally supported from the carrier-frame and adapted to be actuated by contact with the carrier-stop, two gripping-clutches pivotally supported opf posite to each other near the apex of' the pulley guiding walls, spring actuated means Jfor automatically throwing said grippingclutches into locking engagement with the flanges of the pulley as it is drawn between them, one of said gripping-clutches being provided with an operating-arm adapted to bear upon said latch below its pivotal support and the other clutch being provided with an operating-arm adapted to bear against said latch above its pivotal support, whereby as said latch is thrown laterally by contact with the angular wall of the carrier-stop, both of said gripping clutches will be simultaneously thrown out of locking engagement with the pulley and whereby as said pulley is brought in contact with the lower arm of said latch, the upper arm of said latch will be thrown out of engagement with said stop` In testimony whereof I affix my signature in the presence of two witnesses.
